E FFLUVlA-EJECTOR FOR WATER-CLOSETS.

@PECIFICATION forming part of Letters Patent No. 338,794, dated March 30, 1886.

Application filed August 1-1, 1885. Serial No. 174,452. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM SMITH, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful EfiiuviaEjector for \Vater-Closets, of which the following is a specification.

llIy invention relates to an attachment for withdrawing and expelling the e'ffluvia from water-closets, so arranged that the effluvia is sucked or drawn into an intermediate receiver attached to the said closet, and expelled from thence to the soil-pipe; and my invention relates more particularly to certain improvements upon eliiuviaejectors for which Letters Patent of the United States were granted to me on the 15th day of May, 1877.

In the drawings hereto annexed, and which form a part of this specification, Figure 1 is a side elevation of a water-closet with my effiuvia-ejector connected thereunto. Fig. 2 is a plan view of the same. Fig. 3 is a view in section taken through the line 00 m, Fig. 1.

Fig. 4 is a detail view in section, also takenthrough the line 00 a, Fig. 1. Figs. 5 and 6 are views in detail.

Similar letters of reference are used to in dicate like parts throughout the several views.

A represents the bowl of a water-closet,having a circular hollow rim, B, provided with a slit or slot, 0, upon the lower inner side thereof, through which the water is received into the bowl for flushing the closet. The usual soil-pipe, D, is connected to the closet, and extends upward in the form of a dome lead ing downward into the sewer. To one side of this dome is connected an exhaust-chamber,

E, the dome being tapped at F for this purpose. A easing, G, is bolted to the flanges of the exhaust-chamber, within which is placed a valve orplug, H, in which a passage or port,

I, is made in line with the ports J J of the casing. The plug or valve is chambered below the ports of the casing. and a vent, K, connects with the passage J. The valve or plug H is made conical in form, as shown, so as to fit closely within the shell or casing, and it is provided with asuitable stem, which extends up through the seat, to which the handle His connected for operating it. A water-pipe, L, connects with theports J J of the casing, one of which passes downward and enters the exhaust-chamber near its lower end, and to this end is coupled a nipple or nozzle, M, so that when in position a jet of Water is introduced through it into the exhaust-chamber. This nozzle points toward the opening in the soilpipe or dome in the lower end of the exhaustchamber, and a trap, N, is formed by the water from the nozzle, so that foul air from the soil-pipe will not return when the ejector is not in operation. (Shown at Fig. 4.)

An opening, I, is made in the valve-casing, to which is coupled an exhaust-pipe, 0, leading into the hollow slitted rim B of the water-closet above the bowl. Near the point where this exhaust-pipe enters the bowl or hollow slitted rim I connect a water-supply pipe, P, from which water is received with which to flush the closet.

The operation of my improved effluvia-ejector will be as follows, to wit: When the closet is in use, thevalve H is first turned in its shell or casing, which permits the water from the pipe L to enter the exhaust-chamber through the nozzle M, which first expels the water in the trap and then exhausts the air and creates a vacuum in the chamber E, which causes the effluvia or foul air in the bowl or closet to be drawn through the exhaust or foul-air pipe, which enters the chamberthrough the medium of the opening I in the hollow part of the valve, into the chamber E, when the jet of water from the nozzle will drive or force the eiiluvia out into the conduit or lower arm of the dome or soil-pipe. The slitted or slotted rim is of an enlarged construction, so that when the seat of the closet is occupied the suction from the ejector device will draw into the rim the foul air in the basin or bowl, and little, if any,will escape into the apartmentin which the closet is located. During the time, however, of operating the ejector the closet is not to be flushed, or otherwise the valve of the ejector is not to be operated simultaneously with flushing device or pull-handlethat communicates with the valve that admits water to the bowl.

Thus it will be seen that the ejector is connected to the water-closet proper only through the medium of the exhaust-pipe O, and that only one connection is made for flushing the basin or bowl and exhausting the effluvia therefrom. \Vhen the machine is at rest, the

water from the pipe L, after the valve is closed, I

will subsideinto thetrap Nand seal the chanr ber E from the soil-pipe.

Having thus described my invention, what I claim; and desire to secure by Letters Patent,

1. In an effluvia attachment for water-clos' ets, the receiver or exhaust-chamber E, fashioned with a trap, N, in the bottom thereof, and provided with a water-service pipe oper-' ated by a valve or plug above the said exhaustchamber and entering the lower portion of the same, substantially in the manner andfor'the purpose shown and described.

2. In combination with a water-closet, the effluvia-ejector herein described,consistingr of an exhaustchamber having a plug orvalve located above it and a water-service pipe entering at the lower end of'the chamber and provided with ail-nozzle, together with an ex- 20 haust-pipeentering the casingabove the-chamber and connecting with the bowl of the water-closet in themanner as set forth and specified.

3. In a water-closet, the efiluvia exhaust pipe '0 and thevwater pipe P; for flushing the closet, forming a junction with each other at the points shown,whereby the pipes for flushing the closet and exhausting the foul air are combined in one and the same, and form only o
